PAINTERS SCAFYFOLD.

SPECIFICATION forming part of Letters Patent No. 516,606, dated March13, 1894.

Application filed June 21,1893. Serial No. 73M (ITO model.)

To all whom it may concern.-

Be it known that we, LEsTER MANN and FREDERICK L. ANKER, citizens of theUnited States, residing at Albany, in the county of Albany and State ofNew York, have invented certain new and useful Improvements in PaintersScaifolds; and we do hereby declare the following to be a full, clear,and exact description of theinvention, such as will enable othersskilled in the ant to whichit appertains to make and use the same.

Our invention relates to improvements in painters scalfolds, andconsists of the combinations of parts and devices hereinafterparticularly described and set forth in the claims.

The objects of our invention are to provide, in the class of paintersscaffolds, which are supported in front of buildings by suspension, afoot guard at each side of the scaffold, which may operate as a meansfor preventing the feet and legs of persons on the scaffold fromprojecting outwardly over the side edges of the same, and preventindividuals working on it from inadvertantly stepping 0% when theirattention is engaged; and also to provide at the ends and sides of thescaffold guard rails which are jointed with the same so as to be capableof being folded down at will when the scaffold is not in use, and bereadily turned upwardly from the plane of the scaffold to an uprightposition and be secured by suitable devices from being accidentallyturned down, whereby the workmen will be incloscd so as to be preventedfrom accidentally falling from the scaffold. We attain these objects bythe means illustrated in the accompanying drawings forminga part of thisspecification, in which- Figure 1, is a plan view of our improvedscaffold with the guard rails folded down. Fig. 2, is an end view of thesame. Fig. 3 is an end view of the scaffold when the guard rails areturned from a horizontal position as shown in Figs. 1 and 2, to uprightposition for use. Fig. 4 is a plan view of the same. Fig. 5 is anelevation with part shown in section.

The same letters of reference refer to similar parts throughout theseveral views.

In the drawings A represents the scaffold which is composed of the sidesills, a, a, cross bars ofo. and floor boards a a all of which parts maybe made of any suitable wood and be securely joined together by framing,or by means of bolts or rivets as heretofore practicedin theconstruction of swinging painters scaffolds.

B is a foot guard securely fixed in any suit able manner and by any wellknown means to one of the side sills a, so that it may project above theplane of the upper side of the floor boards a to such a distance as toprevent the feet of a person from moving, in a plane with said boards,outwardly past the outer sides of the side sill of the scaffold or anyportion of the person passing over the side of the scaffold as hashappened heretofore in many cases to the great injury of workmen. B is asimilar foot guard, preferably secured to the outer side or street sideof the scaffold, and to the sill a opposite from that to which the footguard B is secured. This sill projects above the plane of the floorboards or. to a distance of three or four inches greater than does theguard B, and like said guard B, this guard B operates to prevent theworkmen from inadvertantly moving his feet backward over the street sideof the scaffold.

O, O, are'end guards which are each hinged or jointed to the ends of thescaffold by suitable hinges c c, as to allow said end guards to be movedfrom a horizontal position when folded on the floor boards asillustrated in Figs. 1 and 2 to upright positions as shown in Figs. 3, 4and 5. These end guards consist each of a foot guard 0, standards a cand horizontal top rail (2 all securely connected together in a rigidand strong manner. The said parts 0 c c and a may be of tubing, yetstrong Wood such as ash or oak-may be employed.

D, is the front side folding guard made with a length equal to thelength of the scaffold and composed of the end posts or standards d dand one or more intermediate standards d, and the longitudinal guard bard supported by the said standards and securely fixed thereto by mortiseand tenon, or by bolts, rivets, corner irons, or other well knowndevices for holding parts of frame work together. This side guard D ishinged or jointed to the foot guard B so as to be capable of beingturned down horizontally as shown in Figs. 1 and 2, and be readilyturned at will from a horizontal or folded position in said figures toan upright position as shown in Figs. 3, 4 and 5. The hinges (1 may havetheir lower strap ends made in the form of angle irons so as tostrengthen the union of the foot guard B with its atta'ched sill a ofthe scaffold, as shown in Figs. 3 and 4.

D is the outer or street side guard composed of posts or standards (Icl, intermediate standards (1, and guard bar d all similar to thecorresponding pieces in guard D, and hinged by hinges d to the footguard B or sill a, or both, by means of an angle form strip as abovedescribed as may be used with guard B and sill a.

E E are fastening devices, by which the respective end guards C 0 whenraised to a vertical position as shown in Figs. 3, 4 and 5, for lockingthe same with the neighboring ends of the side guards D and D as shownin said figures. These fastening devices may be of any suitable form ofconstruction say as hasp and staple with locking pin or key, or bysliding bolts, or by employment of hooks e and staple e.

F, F are stops preferably secured to the ends of the guard bars (1 d andprojecting inwardly to a. short distance so that the rails a may havebearing against the same and not be moved outwardly past the ends ofrails or bars 61 ol and thereby prevent straining the hinges, and holdthese end guards from being moved by any force outwardly past aperpendicular.

G, G are suitable eyes, secured to the scaffold bybolts, clips or otherknown means, for receiving the hooks or equivalent devices used forconnection of the slings or ropes by which the scaffold is to besuspended.

The end guards G O and side guards D, D may be made of metal in tube orother form or of wood or both suitably combined as may be preferred.

The hoisting ropes or slings H H may be of any form of arrangementheretofore used for elevating and suspending the scaffold from thebuilding to be painted from this scaffold.

When the end guards C O and side guards D D are turned from a foldedposition as shown in Figs. 1, and 2, to vertical or upright positions asshown in Figs. 3, t and 5, the workmen on the scaffold will be guardedfrom stepping backward or forward off from the scaffold, and in anytilting of the same they will be prevented from passing over the ends ofthe scaffold. While the workmen are inclosed about by these guards O O DD, the foot guards projected to a short distance above the plane of thefloor boards operates to prevent their feet from passing over the edgesof the scaffold. The openings between the foot guard next the buildingand the top bar or rail of the side guards allow the workmen to workthrough the same down to a line opposite the floor of the scaffold.These improvements add but little to the weight of the scaffold andrender it absolutely safe forthe workmen under all conditions ofsuspension of the same.

Having described our invention, what we claim, and desire to secure byLetters Patent, is-

1. The combination with scaffold A capable of being suspended of footguards B B one of which is projected above the plane of the floor to adistance greater than the other, and side guards D,D constructed asdescribed and jointed with the sides of the scafiold so as to be capableof being folded horizontally at will or turned to vertical positionssubstantially as and for the purposes set forth.

2. The combination with scaffold A, capable of being suspended, footguardsB B, and end guards O O jointed with the ends of the scaifold, soas to be capable of being turned from a horizontal position to avertical one, of the side guards D D hinged to the sides of the scaffoldand capable of being turned from a down folded to avertical one, anddevices for locking the end guards and side guards togethersubstantially as and for the purposes set forth.

In testimony that we claim the invention above set forth we aiiix oursignatures in presence of two witnesses.
